What alternatives to manually writing counters into files exist for PHP developers working on guestbook projects?

Manually writing counters into files for guestbook projects can be tedious and error-prone. An alternative solution is to use a database to store and update the counters dynamically. This allows for easier management and more reliable tracking of guestbook entries. 

// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "guestbook";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Update the counter
$sql = "UPDATE counters SET guestbook_counter = guestbook_counter + 1";
$conn->query($sql);

// Display the counter
$sql = "SELECT guestbook_counter FROM counters";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        echo "Guestbook entries: " . $row["guestbook_counter"];
    }
} else {
    echo "0 results";
}

$conn->close();
